But lithium sulfur batteries have another problem: small molecules of lithium and sulfur form and flow to the lithium, attaching themselves and reducing the battery''s capacity. The membrane needed to allow lithium ions to flow from the lithium to the sulfur and back—and to block the lithium and sulfur particles, known as lithium

Sulfur remains in the spotlight as a future cathode candidate for the post-lithium-ion age. This is primarily due to its low cost and high discharge capacity, two critical requirements for any future cathode material that seeks to dominate the market of portable electronic devices, electric transportation, and electric-grid energy storage.
